We alter carrying capacity when we manipulate resources in a natural environment. If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive. If the population exceeds the carrying capacity for a long period of time, resources may be completely depleted and Then the population size remains relatively the same. If abiotic or biotic factors change, the carrying capacity changes as well. Natural disasters can destroy resources in an ecosystem. ... If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive.
